SPECIFICATION forming part of Letters Patent N 0. 695,340, dated March11, 1902..

Application filedDecember 27, 1901. Serial No, 87,453. (No model.)

To CLZZ whom it may concern:

Be it known that we, WILLIAM PHILIPSON, THOMAS WHIT LE HorwoonPHILIPSON, and PERCY OLARKsoN PHILIPsoN, engineers and 5 machinists,subjects of the King of Great Britaimof Holland Street IronWorks,Astley- Bridge, Bolt-011, in the county of Lancaster, England,have invented certain new and useful Improvements in Life-SavingMechanism for Tramways, of which the following is a specification.

This invention relates to life-saving mechanism for tramways; and itconsists of side and intermediate longitudinal springs disposed on I abar mounted on centers located in bearings secured to the under side ofthe tram-car, the end of each side and intermediate longitudinal springbeing fitted with a sole of either india-rubber or other suitablematerial or substance. This apparatus is connected with a brake of shoeform carried in close proximity to the wheels of a tram-car and held insuspension by adjustable rods, chains, and weights supported from thetram-car and kept from contact with the wheels'of the tram-car when theside and intermediate longitudinal springs are out of action.

Figure 1 is a longitudinal elevation showing our invention applied to atramcar; Fig. 2,

a plan of Fig. 1; Fig. 3, a front view of hanging gate disposed at eachend of a tram-car; Fig. 4:, an enlarged side elevation of tripmotion,showing the same holding the lifesaving mechanism out of action, asindicated on left-hand side of Fig. 1; Fig. 5, an end view of right-handside of Fig; 4; Fig. 6, an enlarged side elevation of trip-motionreleasing the side and intermediate longitudinal springs in case of thehanging gate being ac- 0 tuated by any obstruction met with on thetramway-track, and Fig. 7 an enlarged side view of brake apparatus andits connection with the life-saving apparatus.

A represents so much of the outline of a tram-caras is necessary toillustrate our said invention; B, tram-car wheels; O, axles; D, platformat each end of tram-car; E, bottom framework of tram-car, and G thetramwayrails.

In all the figures the same letters and unmerals are employed toindicate corresponding parts.

To the transverse boards F, disposed on the under side of the tram-carA, are secured by bolts or coach-screws the side frames or fixings H,which are also held, supported, and adjusted by the screwed rods I andnuts J, attached to the cross-bars K, secured in any convenient mannerto the under side of the bottom framework E of the tram-car A. To theside frames or fixings H are pivoted the side and intermediatelongitudinal springs L bythe pins or centers M. The side and intermediate longitudinal springs L are secured to the transverse bar N,fitted with the clips O, pivoted to the side frames or fixings H by thepins or centers M. The front end of each side and intermediatelongitudinal spring L is provided or fitted with the sole P, consistingof either india-rubber, leather, gutta- 7o percha, and the like. Abovethe side and intermediate longitudinal springs L is disposed the canvasbag, cover, or receptacle Q, composed of netting and the like and so arranged as to catch or contain any obstacle that may be met with or rundown when the tram-car A is in motion. The upper end of the canvas bag,cover, or receptacle Q: is attached to the center R, carried by the sideframes or fixings H. The transverse bar N is provided with the uprightS, to which is pivoted the lever T by the pin or center U. The lever Tis provided with the notch a, fitting on the pin or center b, mounted inthe fixing V, secured to the transverse board F by the screws 0. Thelever T extends beyond the notch a and is provided with the adjustableweight d, secured thereto by the setscrew 6, as shown in Fig. 4. Onthepin or center I) are supported the levers f and c, 0 connected attheir upper ends by the pin or center h, on which is mounted the rod i.The other end of the rod i is coupled to the lever j, mounted on theshaft or center 70. The shaft or center 76 is carried from the side 5frames or fixings II by the levers Z, mounted on the centers m. On theshaft or center it are loosely mounted and hung separately the series ofWire, metallic, or other bars WV in such a manner as to allow ofbackward and I00 vertical movements, thereby enabling the bottom ends ofthe said wire, metallic, or other bars W to ride closer to the face ofthe road than hitherto without interfering with the action of the samewhen the tram-car is making a backward movement or in case ofoscillation of the tram-car or when coming into contact with anyobstruction met with on the track or road when the said car is making abackward movement. or center it is fitted with the arm or lever 72,carrying the transverse rod 0, located behind the wire, metallic, orother bars W, by which the latter are held in a vertical position. Thesaid wire, metallic, or other bars W are distanced from each other bythe ferrules 1), disposed on the shaft or center it. Under each step X,leading to and from the tram-car platform D, is disposed the shaft orcenter r, mounted in the bearings or fixings 25, secured to the step Xin any convenient manner. On the shaft or center r are loosely mountedand hung separately the series of wire, metallic, or other bars Y. Eachend of the shaft or center r is fitted with the arm or lever u, carryingthe transverse rod 4;, located behind the wire, metallic, or otherbars'Y, by which the latter are held in a vertical position. The saidwire, metallic, or other bars Y are distanced from each other by theferrules w, disposed on the shaft or center 1. The transverse rod 12 andthe transverse rod 0 are connected together by the chain a: to allow ofthe same actuating the levers n andj and the rod '6, connected to thelever f, mounted on the pin or center I), as shown in Figs. 1 and 4, by

which action the trip-lever y, attached to the lever f, will release thenotch on of the lever T from the center I), as shown in Fig. 6, by whichaction the side and intermediate longitudinal springs L will beliberated and fall down to the position shown on right-hand side of Fig.1, thus enabling the same to catch or contain any obstacle that may bemet with or run down when the tram-carAis in motion.

To insure of the life-saving apparatus above set forth, it is absolutelynecessary that the tram-carshould be stopped with the least possibledelay, which we effect by connecting the same to the brake operating inconjunction with the tram-car wheels B. To the under side of the bottomframework E of the tramcar A are attached on each side in line with thetram-car wheels B the fixings A, secured thereto by the clips B, asshown in Fig. 7. The fixings A are provided with the chainpulleys O,mounted on the pins or centers D, secured to the fixings A in anyconvenient manner. Over the chain-pulleys O are located the chains E,secured to the eyebolts F and-G on the shoes H and balanceweight 1,respectively. The shoes H are connected together by the bar J and boltsK. The shoes H are held out of action when the brake is not required bymeans of the suspended balance-weight I, connected thereto by means ofthe chains E. The bar J is pro- Each end of the shaft.

vided with the weights L, located inside the suspended balance-weight I,for balancing purposes to insure of the shoes 11 assuming their properposition clear of the tram-car wheels B when the brake is out of action.The shoes H on each side of the tram-car A are connected together inpairs by the transverse rods M. On the transverse rods M are located thelongitudinal adjustable rods N, connected to the levers 0, attached tothe shaft P, mounted in the fixings Q, secured to the transverse boardsF. On the shaft P is mounted the lever B, to which is connected thecoupling-rod S by the pin or center T, the other end of the coupling-rodS being connected to the hand-lever U, pivoted to the fixing Y, securedto the platform D, as shown in Figs. 1 and 2. The coupling-rod S isprovided with the projection W, which operates in conjunction with thelever X, carried from the transverse bar N, supporting the side andintermediate longitudinal springs L, by which the tram-car driver orattendant can reset the life-saving mechanism herein set forth by meansof the hand-lever U.

Having now particularly described and ascertained the nature of our saidinvention and in what manner the same is to be performed, we declarethat what we claim is The combination of life-saving mechanism fortramways consisting of the side and intermediate longitudinal springsLwith or without the canvas bag, cover, or receptacle Q-provided attheir outer ends with the soles P; the inner ends being secured to thetransverse bar N fitted with the clips 0 pivoted to the side frames orfixings H by the pins or centers M; the transverse bar N being providedwith the upright S to which is pivoted the lever T having the notch afitting on the pin or center I) mounted in the fixing V carrying theleversfand g and the trip-lever 11 the upper ends of the levers f and 9being connected to the rod t' attached to the leverj mounted on theshaft or center carrying the loosely-mounted and separately-hung seriesof wire, metallic, or other bars W suspended by the levers Z from theouter endsof the side frames or fixings H; the shaft or center 70 havingthe levers 'It carrying the transverse rod 0 connected by the chain 00to the rod 4) located behind the wire, metallic, or other bars Ysuspended under the steps X: the hand-lever U being coupled to the rod Sconnecting with the lever B mounted on the shaft or center P; the rod Shaving the projection W to operate in conjunction with the lever Xcarried from the transverse bar Nsupporting the side and intermediatelongitudinal springs L for resetting the latter: the shaft or center Phaving the levers 0 connected to the longitudinal adjustable rods Nmounted on and connected with the transverse rods M attached to theshoes H; the latter being connected together by the bar J on which aremounted the weights L located inside the balance-weight I, the latterbeing attached to the shoes H I In testimony whereof we have hereuntoset 10 by means of the chains E passing over the our hands in presenceof two subscribing Witchain-pulleys O mounted on the pins or cennesses.
